FIELD OF THE INVENTION

The application discloses redox-active compositions and methods usefulfor treatment, prevention, or suppression of diseases, developmentaldelays and symptoms of pervasive developmental disorders includingautistic spectrum disorders and/or attention deficit/hyperactivitydisorder.

BACKGROUND OF THE INVENTION

Pervasive developmental disorder (PDD) is a category of neurologicaldisorders characterized by severe and pervasive impairment in severalareas of development, including social interaction and communicationsskills. The five disorders under PDD are autistic disorder (autism),Asperger's syndrome, childhood disintegrative disorder (CDD), Rett'sdisorder, and PDD-not otherwise specified (PDD-NOS). Specific diagnosticcriteria for each of these disorders can be found in the Diagnostic &Statistical Manual of Mental Disorders (DSM-IV-TR) as distributed by theAmerican Psychiatric Association (APA). Autistic spectrum disorder (ASD)is an umbrella term that is used to represent a broad heterogeneousdisorder by collectively grouping autistic disorder, Asperger's syndromeand PDD-NOS.

Autism, the most common of the pervasive developmental disorders,affects an estimated 1 in approximately 150 births. Estimates of theprevalence of ASD are in the range of 6.5 to 6.6 per 1000 based onAutism and Developmental Disabilities Monitoring Network Surveillance(Year 2002). Indeed, as of 2003-2004, as many as 1.5 million Americansare believed to have some form of autism. Autism is a childhoodencephalopathy characterized by deficiencies in social interaction andcommunication and by repetitive and stereotyped behaviors. Based onstatistics from the U.S. Department of Education and other governmentalagencies, autism is growing at a rate of 10-17 percent per year. Atthese rates, the Autism Society of America (ASA) estimates that theprevalence of autism could easily reach 4 million Americans in the nextdecade.

Of the other four PDD forms, Asperger's syndrome is closest to autism insigns and likely causes; Rett's disorder and childhood disintegrativedisorder share several signs with autism, but may have unrelated causes;PDD-not otherwise specified (PDD-NOS) is diagnosed when the criteria arenot met for a more specific disorder (Lord C, et al. “Autism spectrumdisorders” Neuron (2000) 28 (2): 355-63).

Autism is a complex serious developmental disability that interfereswith, among other things, the normal development of the brain in theareas of social interaction and communication skills, and which causesseverely restricted interests and repetitive behavior. Typically,autistic children and adults have difficulties in verbal and non-verbalcommunication, social interactions, and leisure or play activities.Autism can include language disorders with impaired understanding,echolalia, pronominal reversal (such as using “you” instead of “I” or“me” when referring to one's self), rituals and compulsive phenomena,and uneven intellectual development with mental retardation. Autisticchildren are also at increased risk of developing seizure disorders,especially during their teen years. Autism typically appears during thefirst three years of life and is the result of a neurological disorderthat affects the functioning of the brain.

The overall incidence of autism is, for the most part, globallyconsistent. Indeed, autism knows no racial, ethnic, or socialboundaries, and family income, lifestyle, and educational levels do notaffect the chance of autism's occurrence. However, it has been found tobe four times more prevalent in boys than girls. On the other hand,Rett's disorder is more prevalent in girls than boys.

Since being first described by Dr. Leo Kanner in 1943, the understandingof autism has grown tremendously. Although autism is defined by acertain set of behaviors, it is a spectrum disorder in that its symptomsand characteristics can be present in a wide variety of combinations,from mild to severe. Therefore, autistic children and adults can exhibitany combination of the behaviors in any degree of severity. Twoindividuals, both with the same diagnosis, may have varying skills anddisplay very different actions. Those only mildly affected may exhibitslight delays in language or communication and may face greaterchallenges in social interactions. For example, one may have difficultyinitiating and/or maintaining a conversation. Communication by autisticchildren or adults is often displayed as talking at others (for example,a monologue on a favorite subject that continues despite attempts byothers to interject comments).

Autism seems to cause those affected by it to process and respond toinformation in unique ways. In some individuals with PDD includingautism, aggressive and/or self-injurious behavior may exist. Thefollowing traits, as identified by the ASA, may also be present inpersons with autism: insistence on sameness or resistance to change;difficulty in expressing needs (i.e. uses gestures or pointing insteadof words); repeating words or phrases in place of normal, responsivelanguage; laughing, crying, or showing distress for reasons not apparentto others; preferring to be alone or an aloof manner; tantrums;difficulty in mixing with others; not wanting to cuddle or be cuddled;little or no eye contact; unresponsive to normal teaching methods;sustained odd play; spinning objects; inappropriate attachments toobjects; apparent over-sensitivity or under-sensitivity to pain; no realfears of danger; marked physical over-activity or extremeunder-activity; uneven gross/fine motor skills; and/ornon-responsiveness to verbal cues (i.e. acts as if deaf although hearingtests in normal range).

Symptoms as in attention deficit hyperactivity disorder (ADHD) arefrequent among individuals with pervasive developmental disorders (PDD).Children meeting diagnostic criteria for a pervasive developmentaldisorder (PDD) display symptoms and impairment related to attentiondeficit hyperactivity disorder (ADHD) sufficient to warrant a diagnosisof ADHD (Goldstein S, et al “The Comorbidity of Pervasive DevelopmentalDisorder and Attention Deficit Hyperactivity Disorder: Results of aRetrospective Chart Review” Journal of Autism and DevelopmentalDisorders, (2004) 34 (3):329-339). Hattori J, et al “Are PervasiveDevelopmental Disorders and Attention Deficit/Hyperactivity DisorderDistinct Disorders?” studied the relationship between patients withattention deficit/hyperactivity disorder (ADHD) and those with pervasivedevelopmental disorders (PDD), using the High-Functioning AutismSpectrum Screening Questionnaire (ASSQ) and ADHD Rating Scale-IV. Thepatients with strictly diagnosed ADHD had many PDD-related symptoms, andthe patients with PDD had many ADHD-related symptoms. It therefore seemsdifficult to make a distinction between ADHD and PDD by using thepresent diagnostic criteria in the DSM-IV.

People with autism have social impairments that appear early inchildhood and continue through adulthood. Autistic infants show lessattention to social stimuli, smile and look at others less often, andrespond less to their own name. Autistic toddlers have more strikingsocial deviance; for example, they have less eye contact andanticipatory postures and are more likely to communicate by manipulatinganother person's hand (Volkmar F, et al “Autism in infancy and earlychildhood,” Annu Rev Psychol (2005) 56: 315-36.) Three- to five-year-oldautistic children are less likely to exhibit social understanding,approach others spontaneously, imitate and respond to emotions,communicate nonverbally, and take turns with others. However, they doform attachments to their primary caregivers. (Sigman M, et al. “Earlydetection of core deficits in autism” Ment Retard Dev Disabil Res Rev.(2004) 10 (4): 221-33). They display moderately less attachment securitythan usual, although this feature disappears in children with highermental development or less severe autism spectrum disorders. Olderchildren and adults with ASD perform worse on tests of face and emotionrecognition (Sigman M. et al, see supra). Contrary to common belief,autistic children do not prefer to be alone. Making and maintainingfriendships often proves to be difficult for those with autism. Forthem, the quality of friendships, not the number of friends, predictshow lonely they are.

Unlike those with autism, people with Asperger's syndrome are notusually withdrawn around others; they approach others, even ifawkwardly, for example by engaging in a one-sided, long-winded speechabout a favorite topic while being oblivious to the listener's feelingsor reactions, such as signs of boredom or haste to leave.

About a third to a half of individuals with autism does not developenough natural speech to meet their daily communication needs; (Noens I,et al, “The ComFor: an instrument for the indication of augmentativecommunication in people with autism and intellectual disability”. JIntellect Disabil Res (2006) 50 (9): 621-32.) Differences incommunication may be present from the first year of life, and mayinclude delayed onset of babbling, unusual gestures, diminishedresponsiveness, and the desynchronization of vocal patterns with thecaregiver. In the second and third years, autistic children have lessfrequent and less diverse babbling, consonants, words, and wordcombinations; their gestures are less often integrated with words.Autistic children are less likely to make requests or share experiences,and are more likely to simply repeat others' words or reverse pronouns.

For individuals with autism, sensory integration problems are common. Inparticular, their senses may be either over- or under-active. The fuzzof a kiwi may actually be experienced as painful; a sweet, fruity smellmay cause a gagging reflex. Some children or adults with autism areparticularly sensitive to sound, so that even the most ordinary dailynoises are painful.

Although there is no single known cause for autism, it is generallyaccepted that it is caused by abnormalities in brain structure orfunction. The shape and structure of the brain in autistic versusnon-autistic children show differences when brain scans are viewed.Currently the links between heredity, genetics and medical problems arebeing investigated by researchers, as well as a number of othertheories. The theory of a genetic basis of the disorder is supported bythe fact that, in many families, there appears to be a pattern of autismor related disabilities. While no one gene has been identified ascausing autism, researchers are searching for irregular segments ofgenetic code that autistic children may have inherited. Whileresearchers have not yet identified a single trigger that causes autismto develop, it also appears that some children are born with asusceptibility to autism.

Other researchers are investigating the possibility that under certainconditions, a cluster of unstable genes may interfere with braindevelopment resulting in autism. Still other researchers areinvestigating problems during pregnancy or delivery as well asenvironmental factors such as viral infections, metabolic imbalances,and exposure to environmental chemicals. Yet other researchers areinvestigating the link between autism and chemical toxicity, inparticular with the mercury-containing vaccine preservative thimerosal.

Some cases of autism have been associated with several different organicconditions, including bioenergetic metabolism deficiency suggested bythe detection of high lactate levels in some patients (Coleman M. et al,Autism and Lactic Acidosis, J. Autism Dev Disord., (1985) 15: 1-8;Laszlo et al Serum serotonin, lactate and pyruvate levels in infantileautistic children, Clin. Chim. Acta (1994) 229:205-207; and Chugani etal., Evidence of altered energy metabolism in autistic children, Progr.Neuropsychopharmacol Biol Psychiat., (1999) 23:635-641) and by nuclearmagnetic resonance imagining as well as positron emission tomographyscanning which documented abnormalities in brain metabolism. Althoughthe mechanism of hyperlactacidemia remains unknown, a likely possibilityinvolves mitochondrial oxidative phosphorylation dysfunction in neuronalcells. A small subset of autistic patients diagnosed with deficienciesin complex I or III of the respiratory chain have been reported in theliterature (see Oliveira, G., Developmental Medicine & Child Neurology(2005) 47 185-189; and Filipek, P A et al., Journal of Autism andDevelopmental Disorders (2004) 34:615-623.) However, in many of thecases of autism where there is some evidence of mitochondrialdysfunction, there is an absence of the classic features associated withmitochondrial disease, such as mitochondrial pathology in muscle biopsy(see Rossignol, D. A. et al., Am J. Biochem. & Biotech, 4 (2) 208-217).

The main goals of treatment are to lessen associated deficits and familydistress, and to increase quality of life and functional independence.No single treatment is best and treatment is typically tailored to thechild's needs. Intensive, sustained special education programs andbehavior therapy early in life can help children acquire self-care,social, and job skills, (Myers S M, et al. “Management of children withautism spectrum disorders” Pediatrics (2007) 120 (5): 1162-82) andAngley M, et al. “Children and autism—part 1—recognition andpharmacological management” Aus.t Fam. Physician (2007) 36 (9): 741-4)and often improve functioning and decrease symptom severity andmaladaptive behaviors; (Rogers S J, et al., “Evidence-basedcomprehensive treatments for early autism” J. Clin. Child Adolesc.Psychol. (2008) 37 (1): 8-38).

Medications have not been proven to correct deficits of ASDs and are notthe primary treatment. They are used to treat problems associated withautism disorders, such as associated maladaptive behaviors orpsychiatric comorbidities that may interfere with educational progress,socialization, health or safety and quality of life. More than half ofU.S. children diagnosed with autistic disorders are prescribedpsychoactive drugs or anticonvulsants, with the most common drug classesbeing antidepressants, stimulants, and antipsychotics. (Oswald D P, etal. “Medication Use Among Children with Autism Spectrum Disorders”. JChild Adolesc Psychopharmacol (2007) 17 (3): 348-55.) Aside fromantipsychotics, there is scant reliable research about the effectivenessor safety of drug treatments for children, adolescents or adults withASD. A person with ASD may respond atypically to medications, themedications can have adverse effects, and no known medication relievesautism's core symptoms of social and communication impairments.Alternative nutritional therapies for autistic children may includeIdebenone and CoQ10, because of their superior antioxidant properties,but no studies have been performed to prove their efficacy.

US Patent Publication 2005/0203066 discloses compounds, compositions andmethods for treatment of developmental delay in cognitive, motor,language, executive function or social skills with a pyrimidinenucleotide precursor, but it does not disclose any compounds,compositions or methods of treatment with compounds of the presentinvention.

Attention deficit hyperactivity disorder (ADHD)—also referred to asADD—is a biological, brain based condition that is characterized by poorattention and distractibility and/or hyperactive and impulsivebehaviors. It is one of the most common mental disorders that develop inchildren. Symptoms may continue into adolescence and adulthood. If leftuntreated, ADHD can lead to poor school/work performance, poor socialrelationships and a general feeling of low self esteem. The mostprevalent symptoms of ADHD are inattention and distractibility and/orhyperactive and impulsive behaviors. Difficulties with concentration,mental focus, and inhibition of impulses and behaviors are chronic andpervasive and impair an individual's daily functioning across varioussettings—home, school or work, in relationships, etc. ADD or attentiondeficit disorder is a general term frequently used to describeindividuals that have attention deficit hyperactivity disorder (ADHD)without the hyperactive and impulsive behaviors. The terms are oftenused interchangeably for both those who do and those who do not havesymptoms of hyperactivity and impulsiveness.

Thus, there is an unmet need for improved methods of treating patientswith pervasive developmental disorders, particularly with autism and/orattention deficit/hyperactivity disorder (ADHD).

SUMMARY OF THE INVENTION

The present invention provides methods and redox-active compositionsthat can reduce the symptoms of autism in a human patient. Briefly, themethods and compositions comprise administering a physiologicallyeffective amount of one or both of in sufficient quantities to reducethe effects of the autism. When administered to human patients sufferingfrom autism, without restriction on the normal diet of the patients, thecompositions and methods reduce or improve one or more symptoms ofautism, such as increased eye contact, better enunciation and use ofpronouns, less fatigue, singing a song for the first time with themelody and words together and the entire song understandable, playingwith age appropriate friends for the first time, fewer tantrums, bettersleep patterns, improved politeness and coordination, being more loving,acknowledging another individual's emotion, and increased voice and wordassociation.

Briefly, the compositions andmethods comprise administering a compound of Formula I, Formula II,Formula III, Formula IV, Formula V, Formula VI, Formula Ia, Formula IIa,Formula IIIa, Formula IVa, Formula Va, Formula VIa, Formula Ib, FormulaIb-R, Formula Ib-S, Formula Ic, Formula Ic-RRR, Formula Ic-SRR, FormulaIc-RSR, Formula Ic-RRS, Formula Ic-SSR, Formula Ic-SRS, Formula Ic-RSS,Formula Ic-SSS, Formula IIIb, Formula IIIc, Formula IIIc-RRR, FormulaIIIc-SRR, Formula IIIc-RSR, Formula IIIc-RRS, Formula IIIc-SSR, FormulaIIIc-SRS, Formula IIIc-RSS, Formula IIIc-SSS, Formula Id, Formula IId,Formula IIId, or Formula IVd to a human patient in sufficient quantitiesto reduce the effects of the autistic disease or of the attentiondeficit disorder. An initial trial wherein compounds of Formula I,Formula II, Formula III, Formula IV, Formula V, Formula VI, Formula Ia,Formula IIa, Formula Ma, Formula IVa, Formula Va, Formula VIa, FormulaIb, Formula Ib-R, Formula Ib-S, Formula Ic, Formula Ic-RRR, FormulaIc-SRR, Formula Ic-RSR, Formula Ic-RRS, Formula Ic-SSR, Formula Ic-SRS,Formula Ic-RSS, Formula Ic-SSS, Formula IIIb, Formula IIIc, FormulaIIIc-RRR, Formula IIIc-SRR, Formula IIIc-RSR, Formula IIIc-RRS, FormulaIIIc-SSR, Formula IIIc-SRS, Formula IIIc-RSS, Formula IIIc-SSS, FormulaId, Formula IId, Formula IIId, or Formula IVd are administered to humanpatients, without restriction on the normal diet of the patients, wouldprovide a significant number of the patients with a significantreduction of one or more symptoms, such as increased eye contact, betterenunciation and use of pronouns, less fatigue, singing a song for thefirst time with the melody and words together and the entire songunderstandable, playing with age appropriate friends for the first time,fewer tantrums, better sleep patterns, improved politeness andcoordination, being more loving, acknowledging another individual'semotion, increased voice and word association.

By “subject,” “individual,” or “patient” is meant an individual, morepreferably a mammal, most preferably a human.

“Treating” a disease with the compounds and methods discussed herein isdefined as administering one or more of the compounds discussed herein,with or without additional therapeutic agents, in order to reduce oreliminate either the disease or one or more symptoms of the disease, orto retard the progression of the disease or of one or more symptoms ofthe disease, or to reduce the severity of the disease or of one or moresymptoms of the disease. “Suppression” of a disease with the compoundsand methods discussed herein is defined as administering one or more ofthe compounds discussed herein, with or without additional therapeuticagents, in order to suppress the clinical manifestation of the disease,or to suppress the manifestation of adverse symptoms of the disease. Thedistinction between treatment and suppression is that treatment occursafter adverse symptoms of the disease are manifest in a subject, whilesuppression occurs before adverse symptoms of the disease are manifestin a subject. Suppression may be partial, substantially total, or total.Because the autism disorders are inherited, genetic screening can beused to identify patients at risk of the disease. The compounds andmethods of the invention can then be administered to asymptomaticpatients at risk of developing the clinical symptoms of the disease, inorder to suppress the appearance of any adverse symptoms.

“Therapeutic use” of the compounds discussed herein is defined as usingone or more of the compounds discussed herein to treat or suppress adisease, as defined above. A “therapeutically effective amount” of acompound is an amount of the compound, which, when administered to asubject, is sufficient to reduce or eliminate either a disease or one ormore symptoms of a disease, or to retard the progression of a disease orof one or more symptoms of a disease, or to reduce the severity of adisease or of one or more symptoms of a disease, or to suppress theclinical manifestation of a disease, or to suppress the manifestation ofadverse symptoms of a disease. A therapeutically effective amount can begiven in one or more administrations.

A “physiologically effective amount” of an active substance indicates anadequate amount of the active substances to have a significant,externally observable effect on the patient. Thus, such aphysiologically effective amount affects one or more of thecharacteristics in the patient without the need for special equipment todetermine the effect. For example, a physiologically effective amount ofa compound of the present invention has a significant, externallyobservable effect on the behavior of the patient by reducing one or moreof the symptoms of autism or other pervasive developmental disorder.Accordingly, one can determine whether an adequate amount of the activesubstance has been administered by watching the patient and observingwhether changes have occurred in the patient due to the activesubstance.

While the compounds described herein can occur and can be used as theneutral (non-salt) compound, the description is intended to embrace allsalts of the compounds described herein, as well as methods of usingsuch salts of the compounds. In one embodiment, the salts of thecompounds comprise pharmaceutically acceptable salts. Pharmaceuticallyacceptable salts are those salts which can be administered as drugs orpharmaceuticals to humans and/or animals and which, upon administration,retain at least some of the biological activity of the free compound(neutral compound or non-salt compound). The desired salt of a basiccompound may be prepared by methods known to those of skill in the artby treating the compound with an acid.

Salts of basic compounds with amino acids, such asaspartate salts and glutamate salts, can also be prepared. The desiredsalt of an acidic compound can be prepared by methods known to those ofskill in the art by treating the compound with a base. Examples ofinorganic salts of acid compounds include, but are not limited to,alkali metal and alkaline earth salts, such as sodium salts, potassiumsalts, magnesium salts, and calcium salts; ammonium salts; and aluminumsalts. Examples of organic salts of acid compounds include, but are notlimited to, procaine, dibenzylamine, N-ethylpiperidine,N,N-dibenzylethylenediamine, and triethylamine salts. Salts of acidiccompounds with amino acids, such as lysine salts, can also be prepared.

The invention also includes all stereoisomers of the compounds,including diastereomers and enantiomers. The invention also includesmixtures of stereoisomers in any ratio, including, but not limited to,racemic mixtures. Unless stereochemistry is explicitly indicated in astructure, the structure is intended to embrace all possiblestereoisomers of the compound depicted. If stereochemistry is explicitlyindicated for one portion or portions of a molecule, but not for anotherportion or portions of a molecule, the structure is intended to embraceall possible stereoisomers for the portion or portions wherestereochemistry is not explicitly indicated.

The compounds can be administered in prodrug form. Prodrugs arederivatives of the compounds, which are themselves relatively inactivebut which convert into the active compound when introduced into thesubject in which they are used by a chemical or biological process invivo, such as an enzymatic conversion. Suitable prodrug formulationsinclude, but are not limited to, peptide conjugates of the compounds ofthe invention and esters of compounds of the inventions.

Clinical Assessment of Autism

Carnitine Deficiency: As documented by Filipek, P A et al, in J, AutismDev. Diosrd. (2004) 34:615-23 serum carnitine levels on 100 childrenwith autism were investigated, concurrently with serum pyruvate,lactate, ammonia, and alanine levels. Values of free and total carnitine(p<0.001), and pyruvate (p=0.006) were significantly reduced whileammonia and alanine levels were considerably elevated (p<0.001) in theautistic subjects. The relative carnitine deficiency in these patients,accompanied by slight elevations in lactate and significant elevationsin alanine and ammonia levels, would suggest that assessing pyruvate,lactate, carnitine and ammonia levels may be useful when measured duringroutine evaluation of ASD children.

Lactic acid (lactate) levels: Some cases of autism have been associatedwith abnormal levels of lactic acid, as pyruvate levels increase andpyruvate is converted to lactate to maintain capacity for glycolysis(see Coleman, M. et al. Journal of Autism and Developmental Disorders(1985) 15, 1-8.) Lactate levels can be measured by taking samples ofappropriate bodily fluids such as whole blood, plasma, or cerebrospinalfluid. Using magnetic resonance, lactate levels can be measured invirtually any volume of the body desired, such as the brain. Wholeblood, plasma, and cerebrospinal fluid lactate levels can be measured bycommercially available equipment such as the YSI 2300 STAT Plus Glucose& Lactate Analyzer (YSI Life Sciences, Ohio).

Lipid Peroxidation: Lipid peroxidation has been found to be elevated inautism indicating that oxidative stress is increased in this disease.Lipid peroxidation can be measured by quantifying the levels ofmalonyldialdehyde (MDA), an end product of fatty acid oxidation. Severalassays exist for MDA in plasma, urine, and other specimens. Such assaysinclude specific reagents for UV detection by HPLC (Steghens, J. P., etal., Free Radic Biol Med (2001) 31:242 and Pilz, J. Chromatogr B BiomedSci appl (2000) 742:315 and capillary electrophoresis (Korizis, K. N. etal., Biomed Chromatogr 15:287 (2001)). A variety of lipid peroxidationproducts including MDA can be quantified using the thiobarbituric acidreaction (K Fukanaga et al., Biomed Chromatogr (1998)12:300).

Lipid peroxidation can also be quantified by measurement of urinarylevels of isoprostane F(2α)-VI, a marker of lipid peroxidation;2,3-dinor-thromboxane B(2), which reflects platelet activation; and6-keto-prostaglandin F(1α), a marker of endothelium activation, by meansof gas chromatography-mass spectrometry in subjects with autism andhealthy control subjects. Methods of detecting oxidant stress-relatedproducts are likewise known in the art. For example, enzyme immunoassaykits are commercially available from Cayman Chemical for determinationof isoprostane F(2α)-VI (Cayman Chemical cat. no. 516301); for2,3-dinor-thromboxane B(2) (Cayman Chemical cat. no. 519051), and for6-keto-prostaglandin F(1α) (Cayman Chemical cat. no. 5152111).

Antioxidant Proteins: Levels of major antioxidant proteins, namelytransferrin (iron-binding protein) and ceruloplasmin (copper-bindingprotein) in the serum, are significantly reduced in autistic children ascompared to their developmentally normal non-autistic siblings. Astriking correlation was observed between reduced levels of theseproteins and loss of previously acquired language skills in childrenwith autism. These results indicate that altered regulation oftransferrin and ceruloplasmin in autistic children who lose acquiredlanguage skills can be used for diagnosis of disease during evaluationof patients.

In one embodiment, the invention also embraces modulating one or moreautism biomarkers, normalizing one or more autism biomarkers, orenhancing one or more autism biomarkers, comprising administering to asubject a therapeutically effective amount or physiologically effectiveamount of one or more compounds or compositions as described herein. Theinvention also embraces compounds and compositions as described herein,which are useful for modulating one or more autism biomarkers,normalizing one or more autism biomarkers, or enhancing one or moreautism biomarkers.

“Autism biomarkers” include free carnitine levels, total carnitinelevels, pyruvate levels, ammonia levels, alanine levels, lactate levels,malonyldialdehyde (MDA) levels, isoprostane F(2α)-VI levels,2,3-dinor-thromboxane B(2) levels, 6-keto-prostaglandin F(1α) levels,transferrin levels and ceruloplasmin levels. These biomarkers can bemeasured in whole blood, serum, plasma, urine, cerebrospinal fluid,cerebral ventricular fluid, or any other biological samples, bodilyfluids, or body compartments.

The compounds and compositions of the invention can be used in subjectsor patients to modulate one or more autism biomarkers. Modulation ofautism biomarkers can be done to normalize autism biomarkers in asubject, or to enhance autism biomarkers in a subject.

Normalization of one or more autism biomarkers is defined as eitherrestoring the level of one or more such autism biomarkers to normal ornear-normal levels in a subject whose levels of one or more autismbiomarkers show pathological differences from normal levels (i.e.,levels in a healthy subject), or to change the levels of one or moreautism biomarkers to alleviate pathological symptoms in a subject.Depending on the nature of the autism biomarker, such levels may showmeasured values either above or below values in non-autistic subjects.For example, carnitine levels are sometimes reduced in autistic subjectsin comparison to non-autistic subjects, and an increase in the carnitinelevel may be desirable. Ammonia levels are sometimes higher in autisticsubjects in comparison to non-autistic subjects, and a decrease inammonia levels may be desirable. Normalization of autism biomarkers caninvolve restoring the level of autism biomarkers of an autistic subjectto within about at least two standard deviations of the non-autisticvalue, more preferably to within about at least one standard deviationof the non-autistic value, to within about at least one-half standarddeviation of the non-autistic value, or to within about at leastone-quarter standard deviation of the non-autistic value.

When an increase in an autism biomarker level is desired to normalizethe one or more such autism biomarkers, the level of the autismbiomarker in an autistic subject can be increased to within about atleast two standard deviations of the value in a non-autistic subject,more preferably increased to within about at least one standarddeviation of the non-autistic value, increased to within about at leastone-half standard deviation of the non-autistic value, or increased towithin about at least one-quarter standard deviation of the non-autisticvalue, by administration of one or more compounds or compositionsaccording to the invention. Alternatively, the level of one or more ofthe autism biomarkers can be increased by about at least 10% above thesubject's level of the respective one or more autism biomarkers beforeadministration, by about at least 20% above the subject's level of therespective one or more autism biomarkers before administration, by aboutat least 30% above the subject's level of the respective one or moreautism biomarkers before administration, by about at least 40% above thesubject's level of the respective one or more autism biomarkers beforeadministration, by about at least 50% above the subject's level of therespective one or more autism biomarkers before administration, by aboutat least 75% above the subject's level of the respective one or moreautism biomarkers before administration, or by about at least 100% abovethe subject's level of the respective one or more autism biomarkersbefore administration.

When a decrease in a level of one or more autism biomarkers is desiredto normalize the one or more autism biomarkers, the level of the one ormore autism biomarkers in an autistic subject can be decreased to alevel within about at least two standard deviations of the value in anon-autistic subject, more preferably decreased to within about at leastone standard deviation of the value in a non-autistic subject, decreasedto within about at least one-half standard deviation of the value in anon-autistic subject, or decreased to within about at least one-quarterstandard deviation of the value in a non-autistic subject, byadministration of one or more compounds or compositions according to theinvention. Alternatively, the level of the one or more autism biomarkerscan be decreased by about at least 10% below the subject's level of therespective one or more autism biomarkers before administration, by aboutat least 20% below the subject's level of the respective one or moreautism biomarkers before administration, by about at least 30% below thesubject's level of the respective one or more autism biomarkers beforeadministration, by about at least 40% below the subject's level of therespective one or more autism biomarkers before administration, by aboutat least 50% below the subject's level of the respective one or moreautism biomarkers before administration, by about at least 75% below thesubject's level of the respective one or more autism biomarkers beforeadministration, or by about at least 90% below the subject's level ofthe respective one or more autism biomarkers before administration.

Enhancement of the level of one or more autism biomarkers is defined aschanging the extant levels of one or more autism biomarkers in anautistic subject to a level which provides beneficial or desired effectsfor the subject. Additional enhancement, beyond normalization, may benecessary in the event that normalizing the level of one or more autismbiomarkers does not suffice to bring about an improvement in symptoms.

Accordingly, when an increase in a level of one or more autismbiomarkers is beneficial to an autistic subject, enhancement of the oneor more autism biomarkers can involve increasing the level of therespective autism biomarker or autism biomarkers in the autistic subjectto about at least one-quarter standard deviation above the value in anon-autistic subject, about at least one-half standard deviation abovethe value in a non-autistic subject, about at least one standarddeviation above the value in a non-autistic subject, or about at leasttwo standard deviations above the value in a non-autistic subject.Alternatively, the level of the one or more autism biomarkers can beincreased by about at least 10% above the subject's level of therespective one or more autism biomarkers before enhancement, by about atleast 20% above the subject's level of the respective one or more autismbiomarkers before enhancement, by about at least 30% above the subject'slevel of the respective one or more autism biomarkers beforeenhancement, by about at least 40% above the subject's level of therespective one or more autism biomarkers before enhancement, by about atleast 50% above the subject's level of the respective one or more autismbiomarkers before enhancement, by about at least 75% above the subject'slevel of the respective one or more autism biomarkers beforeenhancement, or by about at least 100% above the subject's level of therespective one or more autism biomarkers before enhancement.

When a decrease in a level of one or more autism biomarkers is desiredto enhance one or more autism biomarkers, the level of the one or moreautism biomarkers in an autistic subject can be decreased by an amountof about at least one-quarter standard deviation of the value in anon-autistic subject, decreased by about at least one-half standarddeviation of the value in a non-autistic subject, decreased by about atleast one standard deviation of the value in a non-autistic subject, ordecreased by about at least two standard deviations of the value in anon-autistic subject. Alternatively, the level of the one or more autismbiomarkers can be decreased by about at least 10% below the subject'slevel of the respective one or more autism biomarkers beforeenhancement, by about at least 20% below the subject's level of therespective one or more autism biomarkers before enhancement, by about atleast 30% below the subject's level of the respective one or more autismbiomarkers before enhancement, by about at least 40% below the subject'slevel of the respective one or more autism biomarkers beforeenhancement, by about at least 50% below the subject's level of therespective one or more autism biomarkers before enhancement, by about atleast 75% below the subject's level of the respective one or more autismbiomarkers before enhancement, or by about at least 90% below thesubject's level of the respective one or more autism biomarkers beforeenhancement.

EXAMPLE Screening Compounds of the Invention in Human Dermal Fibroblastsfrom Autistic Patients

A screen was performed to identify compounds effective for theamelioration of ASD. Test samples, and solvent controls were tested fortheir ability to rescue ASD fibroblasts stressed by addition ofL-buthionine-(S,R)-sulfoximine (BSO).

MEM (a medium enriched in amino acids and vitamins, catalog no. Gibco11965) and Fetal Calf Serum were obtained from Invitrogen. Basicfibroblast growth factor and epidermal growth factor were purchased fromPeproTech. Penicillin-streptomycin-glutamine mix, L-buthionine(S,R)-sulfoximine, and insulin from bovine pancreas were purchased fromSigma. Calcein AM was purchased from Molecular Probes. Cell culturemedium (ATP) was made by combining 75 ml Fetal Calf Serum, 100 U/mlpenicillin, 100 μg/ml streptomycin, 2 mM glutamine, 10 ng/ml EGF, and 10ng/ml bFGF; MEM EBS was added to make the volume up to 500 ml. A 10 mMBSO solution was prepared by dissolving 444 mg BSO in 200 ml of mediumwith subsequent filter-sterilization. During the course of theexperiments, this solution was stored at +4° C. The cells were obtainedfrom Dr. J. M. Shoffner, Medical Neurogenetics, Atlanta, Ga. and weregrown in 10 cm tissue culture plates. Every week, they were split at a1:3 ratio.

The samples were supplied in 1.5 ml glass vials. The compounds werediluted with DMSO, ethanol or PBS to result in a 5 mM stock solution.Once dissolved, they were stored at −20° C.

The samples were screened according to the following protocol: A culturewith ASD fibroblasts was started from a 1 ml vial with approximately500,000 cells stored in liquid nitrogen. Cells were propagated in 10 cmcell culture dishes by splitting every week in a ratio of 1:3 until nineplates were available. Once confluent, fibroblasts were harvested. For54 micro titer plates (96 well-MTP) a total of 14.3 million cells(passage eight) were re-suspended in 480 ml medium, corresponding to 100μl medium with 3,000 cells/well. The remaining cells were distributed in10 cm cell culture plates (500,000 cells/plate) for propagation. Theplates were incubated overnight at 37° C. in an atmosphere with 95%humidity and 5% CO₂ to allow attachment of the cells to the cultureplate.

MTP medium (243 μl) was added to a well of the microtiter plate. Thetest compounds were unfrozen, and 7.5 μl of a 5 mM stock solution wasdissolved in the well containing 243 μl medium, resulting in a 150 μMmaster solution. Serial dilutions from the master solution were made.The period between the single dilution steps was kept as short aspossible (generally less than 1 second).

Plates were kept overnight in the cell culture incubator. The next day,10 μl of a 10 mM BSO solution were added to the wells, resulting in a 1mM final BSO concentration. Forty-eight hours later, three plates wereexamined under a phase-contrast microscope to verify that the cells inthe 0% control (wells E1-H1) were clearly dead. The medium from allplates was discarded, and the remaining liquid was removed by gentlytapping the plate inversed onto a paper towel.

100 μl of PBS containing 1.2 μM Calcein AM were then added to each well.The plates were incubated for 50-70 minutes at room temperature. Afterthat time the PBS was discarded, the plate gently tapped on a papertowel and fluorescence (excitation/emission wavelengths of 485 nm and525 nm, respectively) was read on a Gemini fluorescence reader. Data wasimported into Microsoft Excel (EXCEL is a registered trademark ofMicrosoft Corporation for a spreadsheet program) and used to calculatethe EC₅₀ concentration for each compound.

The compounds were tested three times, i.e., the experiment wasperformed three times, the passage number of the cells increasing by onewith every repetition.

The solvents (DMSO, ethanol, PBS) neither had a detrimental effect onthe viability of non-BSO treated cells nor did they have a beneficialinfluence on BSO-treated fibroblasts even at the highest concentrationtested (1%). None of the compounds showed auto-fluorescence. Theviability of non-BSO treated fibroblasts was set as 100%, and theviability of the BSO- and compound-treated cells was calculated asrelative to this value.

Certain compounds of the present invention such as:2,3,5-trimethyl-6-nonylcyclohexa-2,5-diene-1,4-dione and2-(3-hydroxy-3,7,11,15-tetramethylhexadeca-6,10,14-trienyl)-3,5,6-trimethylcyclohexa-2,5-diene-1,4-dioneand 2,3,5-trimethyl-6-nonylcyclohexa-2,5-diene-1,4-dione exhibitedprotection against ASD with an EC₅₀ of less than about 150 nM.
